Server components vs client components decisions in the Next.js App Router depend on whether the UI requires interactivity or direct data fetching. Use server components for static rendering and data access, and client components for state and event handling.

Data fetching in Next.js App Router supports default static rendering, Incremental Static Regeneration (ISR), and on-demand no-store strategies. Choose based on how frequently your data changes and whether you need real-time cache invalidation.

Organize Next.js App Router routing using file conventions, route groups for logical separation, parallel routes for simultaneous rendering, and intercepting routes to handle modals cleanly.

Yes, the App Router patterns apply across small to large Next.js apps. The guidance covers modular routing organization, server and client component boundaries, and performance optimizations suited for scaling.

Optimize Next.js App Router performance by strategically moving interactivity to client components, leveraging server components for data fetching, and applying appropriate caching strategies like ISR or no-store for dynamic content.
